Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices (SRD); Equipement for Detection and Movement; Tanks Level Probing Radar (TLPR) operating in the frequency bands 5@8 GHz@ 10 GHz@ 25 GHz@ 61 GHz and 77 GHz; Part 2: Harmoni
The present document specifies the requirements for Tank Level Probing Radar (TLPR) applications based on pulse RF@ FMCW@ or similar wideband techniques. The radar applications in the present document are limited to TLPRs operating as short range devices@ in which the devices are installed in closed metallic tanks or reinforced concrete tanks@ or similar enclosure structures made of comparable attenuating material@ holding a substance@ liquid or powder. TLPRs are only used for tank level measurement applications where TLPRs are radiating RF signals directly from the tank top downwards to the surface of a substance contained in a closed tank. Any radiation outside of the tank is caused by leakage and is considered as unintentional emission. In addition to the present document@ other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the RTTE Directive [1] may apply to equipment within the scope of the present document. NOTE: A list of such ENs is included on the web site: http://www.newapproach.org/.
